I've owned a Tosh 32WL48 for a few weeks now and thought I had a good picture after some tweaking. I had a problem with a buzzing noise though, that disapears when I turn the backlight up to 75% or above. This has led to me tweak the settings all over again and I'm not quite there yet I think. Having seen a few people mentioning set-up DVDs such as DVE or Avia I'd like to know if anyone rates these for setting up an LCD. Also, they seem to be available for R1 or R2 DVDs. I assume I would want an R2 one, but does it actually matter if my set can handle NTSC input? Is it useful for setting up Sky+ input?
